How does the inflatable Indominus Rex costume stay inflated?

It uses a small, battery-operated fan that continuously blows air into the suit. You must keep the zipper fully closed and the elastic bands at the wrists and ankles snug to maintain pressure.

Can you see and breathe easily inside the inflatable suit?

Yes, the suit features a clear plastic viewing window near the neck/mouth area, and the constant airflow from the fan provides fresh air.

How do I make a DIY Indominus Rex costume?

Use a white hoodie and sweatpants as your base. Cut jagged teeth and back spikes from grey craft foam, glue them to the hood and spine, and paint red dinosaur eyes on the sides of the hood.

The look is most famously achieved using an official inflatable suit, but it can also be built using a detailed jumpsuit and mask.

How to put it together

1
If using the inflatable suit, insert fresh AA batteries into the fan pack and clip it to your waistband.
2
Step into the legs of the suit, slip your arms into the sleeves, and pull the hood or headpiece over your head.
3
Zip the suit completely closed to seal the air inside, then turn on the fan switch to begin inflation.
4
Adjust the face opening or viewing panel so you have clear, unobstructed peripheral vision.
5
If going the fabric route, put on your white base layers, attach your DIY foam spikes, and don the mask and claw gloves.
6
Practice your best low-frequency hybrid dinosaur growl and stomping walk.

Makeup & hair

If wearing the inflatable suit or full mask, no makeup or hair styling is needed. For a maskless DIY look, paint your face with white and grey face paint to mimic scales, and use red cosmetic contacts for the eyes.
